Abstract
Description
Technical Field
[0001] This utility model relates to a freeze-dried powder packaging container, specifically a puncture-and-spray freeze-dried powder bottle with an exhaust device. Background Technology
[0002] Freeze-dried powder is a skincare product made using freeze-drying technology. It is typically sold and used in conjunction with a specially formulated solvent. The finished freeze-dried powder is packaged in a medicine bottle, which also contains a medicine bottle with the solvent. To use, both the freeze-dried powder bottle and the solvent bottle are opened separately, and the solvent is poured into the freeze-dried powder bottle, mixed, and then used.
[0003] Because using two bottles is cumbersome, many manufacturers have begun developing dual-chamber containers that can separately hold lyophilized powder and solvent liquid. Detailed structures can be found in Chinese utility model patent publication number CN221024755U. This technical solution involves a first chamber and a second chamber within the container. The first chamber stores the outer solution medium of the cosmetic, while the second chamber stores the lyophilized powder medium. A movable sealing seat with aluminum foil is installed inside the container. The aluminum foil effectively isolates the first and second chambers. The two ends of the movable sealing seat can slide up and down inside the outer bottle, causing the aluminum foil to move towards the piercing post. This allows the piercing post to pierce the aluminum foil, connecting the first and second chambers. The outer solution stored in the first chamber flows into the second chamber and mixes with the lyophilized powder, resulting in a freshly mixed active cosmetic solution. This structure allows for simple and rapid mixing of lyophilized powder and has gained market acceptance. However, during use, it has been found that the dispensing nozzle is prone to spraying, leading to material waste. The inventor discovered that the reason the nozzle sprays material is that after the sharp-edged pin pierces the aluminum foil seal to connect the two chambers, the air inside the chambers is compressed due to the constant sealing between them, increasing the pressure inside the bottle. When the cap is opened, the pressure difference between the inside and outside of the bottle causes the material to be sprayed outwards. Therefore, the inventor improved the above structure. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a puncture-and-spray freeze-dried powder bottle with an exhaust device.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A spiking lyophilized powder bottle with an exhaust device, comprising:
[0007] The first cavity has a sealing film at its opening;
[0008] The second cavity is arranged opposite to the first cavity, and the opening of the second cavity is provided with a puncture hole facing the sealing film;
[0009] A connector, wherein a cavity is provided inside the connector, one end of the cavity is connected to the opening of the first cavity, and the other end of the cavity is slidably engaged with the piercing opening of the second cavity;
[0010] The first cavity or the second cavity is provided with a discharge nozzle;
[0011] A sealing component is provided between the puncture opening and the inner wall of the cavity. The outer surface of the puncture opening is provided with a sealing surface that cooperates with the sealing component. The sealing surface is divided into a lower sealing surface, an exhaust groove area, and an upper sealing surface from bottom to top. The exhaust groove area is provided with at least one exhaust groove arranged from top to bottom.
[0012] Before the puncture port punctures the sealing film, the lower sealing surface and the sealing component are in a sealing fit.
[0013] After the puncture hole completely punctures the sealing film, the upper sealing surface and the sealing component are sealed together.
[0014] The connector is provided with an exhaust hole that connects the external atmosphere and the internal cavity. During the process of the piercing port piercing the sealing film, the exhaust groove area cooperates with the sealing component, and the exhaust hole and the exhaust groove form an exhaust channel that connects the external atmosphere with the first cavity and the second cavity.
[0015] In this invention, the sealing component includes a sealing body and a sealing ring. The sealing body is disposed at the opening of the first cavity, and the sealing ring mates with the sealing surface. The height of the sealing ring is less than the height of the exhaust groove.
[0016] In this invention, an exhaust gap is provided between the sealing body and the sealing surface, and the exhaust hole, exhaust groove and exhaust gap form an exhaust channel connecting the external atmosphere with the first cavity and the second cavity.
[0017] In this invention, the inner wall of the cavity is provided with an exhaust chamber facing the sealing surface, and the exhaust chamber is located above the sealing component.
[0018] In this utility model, the connector is further provided with a piercing rotary switch, and the connector is provided with an insertion hole for the piercing rotary switch to be inserted into. The gap between the piercing rotary switch and the insertion hole forms an exhaust hole.
[0019] In this invention, a cover is fitted on the outer side of the discharge nozzle.
[0020] The beneficial effects of this invention are as follows: Before the piercing port breaks through the sealing film, the lower sealing surface of the piercing port is sealed to the sealing component, ensuring that the first and second cavities of the bottle are sealed and preventing leakage of the raw materials inside. During the downward movement of the piercing port to break through the sealing film, the venting groove area enters the mating surface of the sealing component. At this time, the first and second cavities are connected to the external atmosphere through the venting channel. As the second cavity moves downward, excess gas is discharged from the venting channel, making the internal pressure equal to that of the external atmosphere, effectively preventing material spraying from the dispensing nozzle.

[0033] Reference Figures 1 to 11 This embodiment provides a puncture-resistant lyophilized powder bottle with an exhaust device, comprising an upper bottle body and a lower bottle body, wherein the lower bottle body is provided with a first cavity 1 for storing lyophilized powder. (See attached...) Figure 4 Looking at the direction, a sealing film 11 is provided at the opening of the upper part of the first cavity 1; the upper bottle body is provided with a second cavity 2 for storing solvent liquid, the second cavity 2 is arranged opposite to the first cavity 1, and the opening of the second cavity 2 is provided with a piercing hole 21 facing the sealing film 11. The piercing hole 21 is cylindrical with a beveled bottom, thus forming a piercing head. Here, the upper bottle body can also be used to store solvent liquid, and the lower bottle body can be used to store lyophilized powder, achieving the same technical effect.
[0034] The second cavity 2 is provided with a discharge nozzle 4, and a cover 7 is fitted over the outside of the discharge nozzle 4. A plug is provided inside the cover 7 to press against the discharge nozzle 4 to increase the sealing performance. The discharge nozzle 4 can also be provided only on the first cavity 1, which has the same technical effect.
[0035] The upper and lower bottle bodies are connected to each other by a connector 3. The connector 3 has a through cavity 31. The lower end of the cavity 31 is connected to the opening of the first cavity 1, and the opening of the first cavity 1 is connected to the inner wall of the cavity 31 by a snap-fit. The other end of the cavity 31 is slidably engaged with the piercing opening 21 of the second cavity 2. The cavity 31 has a first engaging channel 311, a second engaging channel 312, and a third engaging channel 313. The inner diameter of the first engaging channel 311 is larger than the inner diameter of the second engaging channel 312. A first limiting protrusion 314 protrudes inward between the first engaging channel 311 and the second engaging channel 312. The upper bottle body has a first engaging section 111 that engages with the first engaging channel 311, a second engaging section 112 that engages with the first limiting protrusion 314, a third engaging section 113 that engages with the second engaging channel 312, and a fourth engaging section 114 that engages with the third engaging channel 313. The inner diameter of the first limiting protrusion 314 is larger than the outer diameter of the third mating section 113, preventing the upper bottle from being pulled out of the connector 3 and thus constituting a limiting structure for the upper bottle to move upward. The inner diameter of the first limiting protrusion 314 is smaller than the outer diameter of the first mating section 111, preventing the first mating section 111 from moving downward and thus constituting a limiting structure for the upper bottle to move downward.
[0036] In this embodiment, a sealing component 5 is provided between the piercing opening 21 and the inner wall of the cavity 31. The outer side of the sealing component 5 is connected to the inner wall of the cavity 31. The outer surface of the piercing opening 21 is provided with a sealing surface that mates with the sealing component 5. The sealing surface is located below the fourth mating section. The sealing surface is divided into a lower sealing surface 211, an exhaust groove area 212, and an upper sealing surface 213 from bottom to top. The exhaust groove area 212 is provided with at least one exhaust groove arranged from top to bottom, and the exhaust groove is recessed into the sealing surface. The sealing component 5 includes a sealing body 51 and a sealing ring 52. The sealing body 51 is disposed at the opening of the first cavity 1. The sealing ring 52 mates with the sealing surface, and the height of the sealing ring 52 is less than the height of the exhaust groove. Before the piercing opening 21 pierces the sealing film 11, the lower sealing surface 211 and the sealing component 5 are sealed together to ensure the sealing of the first cavity 1 and the second cavity 2. The connector 3 is provided with an exhaust port 32 that connects the external atmosphere and the internal cavity 31. The exhaust port 32 is located within the third mating section. During the process of the piercing port 21 piercing the sealing film 11, the exhaust groove area 212 mates with the sealing component 5, and the exhaust port 32 and the exhaust groove form an exhaust channel connecting the external atmosphere with the first cavity 1 and the second cavity 2. After the piercing port 21 completely pierces the sealing film 11, the upper sealing surface 213 seals with the sealing component 5, preventing the mixed material inside from flowing out of the exhaust channel.
[0037] In a preferred embodiment, an exhaust gap 53 is provided between the sealing body 51 and the sealing surface. When the puncture port 21 punctures the sealing film 11, the exhaust gap 53 faces the lower sealing surface 211. The exhaust hole 32, the exhaust groove and the exhaust gap 53 form an exhaust channel that connects the external atmosphere with the first cavity 1 and the second cavity 2.
[0038] In a preferred embodiment, the inner wall of the cavity 31 is provided with an exhaust chamber 33 facing the sealing surface. The exhaust chamber 33 is a groove recessed into the inner wall of the third mating channel. The exhaust chamber 33 is located below the third mating channel and above the sealing component 5. The exhaust chamber 33 communicates with the exhaust hole 32. The exhaust hole 32, the exhaust chamber 33, the exhaust groove, and the exhaust gap 53 form an exhaust channel connecting the external atmosphere with the first cavity 1 and the second cavity 2.
[0039] In this embodiment, the connector 3 is also provided with a piercing rotary switch 6. Here, the piercing rotary switch 6 can have several structural configurations. One is a driving structure that drives the piercing port 21 downwards. The piercing rotary switch 6 is rotatably connected to the connector 3. One end of the piercing rotary switch 6 has a handle, and the other end has a lever. The upper bottle body has a mating block that cooperates with the lever. Before the handle is rotated, the lever and the mating block are engaged, so even if the upper bottle body is pressed down, it cannot move downwards. When the handle is rotated, the lever drives the mating block downwards, thereby driving the piercing port 21 downwards. The piercing rotary switch 6 can also be a blocking structure that prevents the upper and lower bottle bodies from moving relative to each other. The piercing rotary switch 6 is rotatably connected to the connector 3. One end of the piercing rotary switch 6 has a handle, and the other end has a stop block. The upper bottle body has a pressing block that cooperates with the stop block. Before the handle is rotated, the stop block and the pressing block are engaged, so even if the upper bottle body is pressed down, it cannot move downwards. After rotating the handle, the entire outer side of the piercing rotary switch 6 moves, disengaging the stop block from the pressure block. Pressing down on the upper bottle body then causes the piercing port 21 to pierce the sealing film 11. Regardless of the specific structure of the piercing rotary switch 6, the connector 3 has an insertion hole for the piercing rotary switch 6 to be partially inserted. This insertion hole is located below the third mating channel, and the mating gap between the piercing rotary switch 6 and the insertion hole forms a vent 32. Therefore, the connector 3 does not require an additional separate vent 32, making product processing easier.
[0040] The working principle of this utility model is as follows: The first chamber 1 contains freeze-dried powder, and the second chamber 2 contains solvent liquid. Before the piercing port 21 pierces the sealing film 11, the lower sealing surface of the piercing port 21 is sealed with the sealing component. The first chamber 1 is sealed by the sealing film 11, and a sealing gasket is provided at the connection between the first chamber 1 and the connecting piece 3. The upper end of the discharge nozzle 4 of the second chamber 2 is sealed by the cover 7, and the lower end of the second chamber 2 is sealed by the sealing film 11, the sealing gasket, and the sealing component. As the piercing port 21 moves downward to pierce the sealing film 11, the solvent liquid in the second chamber 2 falls into the first chamber 1 under gravity. At the same time, the exhaust groove area 212 enters the mating surface of the sealing ring 52. The first chamber 1 and the second chamber 2 are connected to the external atmosphere through the exhaust channel. As the second chamber 2 moves downward, excess gas is discharged from the exhaust channel, making the internal pressure consistent with the external atmosphere, effectively preventing the discharge nozzle 4 from spraying out.
[0041] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
